I am putting in a 350 2-bolt roller cam motor with either 810, 191 or 193 heads (remanufacturer uses all 3 and I don't know which ones I will get), stock TPI setup except I'm making a better CAI, 24 lb. injectors, custom prom with hotter fuel and timing curve, Hooker 2055s, Magnaflow hi-flow cat, Hooker cat-back, Dana's "modified" TransGo shift kit for the 700r4, 3.23 gears going in the rear end.

Just wondering what to expect. 275? That's about what I think ... I'd like to know what the TPI experts think.

if they bored it 30 over its a 383 so 275 should be easy,later jimmy

only if they also added a 3.75" stroke. else just bored is 355.



The question is what cam is in the motor your getting?

stock L98 cam makes that motor basically a stock L98 TPI with some exhaust mods and a tune. Thats near 235-240 at the wheels. Somewhere around 275-280 crank hp

bigger cam could see 250-260 depending on what it is. thats around 300-320 crank hp

No, it's not a 383 'cause it has the orig. 350 crank ... not a 400 crank. But, yes, it's bored .030 over. So that makes it a 355? Didn't take the extra displacement into consideration. Sweet.

Cam is the stock L98.

Can you swap in a (slightly) bigger cam without a prom tune? I don't want to get into DIY promming. I'm somewhat of a computer geek, but I think it seems a bit tedious to learn.

I could have had the reman. port/polish the heads but it would have been an extra $400. I'm already tying up more in this car than I wanted, but now that I have the bug, money is going fast. And, since I'm running the stock TPI, I figure I've got more than enough restriction there to nullify the benefits of head porting. Would I be correct or did I mess up?

I would be happy with 250 at the rear wheels. I'm not looking for a screamer. I want a fun, streetable car that I can take to cruise-ins on the weekends or take on a 6-hr. drive to the beach with the wife and kid.

Anything is better than that dog-of-a-305 that's getting yanked. I can't believe GM put 305 TPIs (or worse TBIs!!!) w/ 2.73 rear ends in their "performance" cars. My wife's '05 Volvo S60 in-line Turbo 5-banger can smoke my T/A as it is now.

And why did these cars never come from the factory with headers? That's the only page out of Ford's book that I wish GM would have copied. (Correct me if I'm wrong ... I don't know Fords too well ... but I thought that Mustangs came from the plant with headers.)

Oh, and I've decided that if I ever get the "more go" bug later on, I'm saving my money for a turbo kit. All it takes is a new prom tune and a lot of cash.

forgot about the stroke, its been a looonnnggg day, thanksorr89rocz. with what you say it has it should be a good reliable streetable engine,later jimmy

Hey Jimmy, where is Oxford, NC? I'm in Morganton 'bout an hour east of Asheville.[\edit]

250whp will need a larger cam. A maf can tolerate more of a cam than a SD setup. You can setup up alittle bit but i dont think its worth the gains with out tuning. 250whp will need more bolt ons like bigger TPI stuff and a tune would really help pickup torque with more aggressive timing curve.

no big deal tho, your probly sitting around 235whp and thats MORE than enough to run mid 13's. thats where i was before i went HSR

gcgarner

HSR ... is that Super Ram? How much did that setup run you?

Orr89RocZ

HSR= HOlley Stealth Ram

runs about 650 with everythign to bolt in

gogarner ,im on the virginia line, little town called virgilina,about 3 hrs from you.later jimmy

Thought long and hard about a cam swap today.

Comp 08-502 was what I was thinking.

Would I need another prom tune for that?

What kind of HP gains would it give me?

Would I need to change anything else (with valve train) or get the recommended stall converter?

Price is around $260 and I don't want to spend that if its not significant gains.

If you have the cash, do urself the favor and get a HSR

I believe that cam is a bit big if ur not wanting to tune.

Orr89RocZ

I think its capable of handling that cam on stock tune but its gonna run abit "off" compared to when its tuned. You could try it and order a mail order tune for 200 bucks. I'd buy my own tuning stuff tho for 250 and start working on it.

502 cam is a nice grind for stock TPI tho. works well with a HSR as well but i'd like the 503 cam for the HSR and stock heads I like aggressive street setups tho.

gcgarner

So you're suggesting the HSR over the cam swap? Wouldn't I need to tune with the Stealth Ram?

Orr89RocZ

iTrader: (20)

thats another thing... i'm not sure how well speed density reacts to those mods. I think you could get away with the HSR on that motor without much tuning other than fuel pressure and base timing adjustments.

Cam may run fine on that setup too with those adjustments but even stock motors can benefit from a tune, so a cammed or bolt on car can pick up more with a tune

billybird

not to thread jack or anything lol..but what about a 305 tpi with comp cams 262(a step above the lt1 cam) and trick flow super 23's 175 intake 67 exhuast 56cc and slp runners would make?

gcgarner

Just wise up like I did and ditch the dog.

I think a 350 swap is the best bang-for-the-buck mod available for our cars.

You can spend a bunch of money on those mods to a 305, but in the end, you still have a 305. I fought with myself over the same dilemma for two years, and I finally decided that no matter what I do to my 305, it is still just that.

Now, don't get me wrong. I will keep my 305 around in case I ever want to put my car back to original (if it ever realizes any collector value where original would be worth more than rodded).

Check out this link. This is where I got my motor: 350 TPI

$1,264 out the door for the long block plus $175 shipping (and I had to pay the $225 core charge). But they offered to port the heads for $400 and will paint it any color you want for $10.

Throw in another $300 for injectors, $35 for a knock sensor and $100 for a custom prom, and you've got yourself something nice for around $2k.

Then do what I did and drop about $900 into the exhaust. You can do all the aftermarket heads and cam you want, but if it don't flow, it don't go.
